Vibration-damping seat

Abstract

The invention provides a vibration-damping seat which belongs to the technical field of machinery. The invention solves the technical problems of poor vibration-damping effect, easy exposure to directional influence of impact force and the like found in the vibration-damping seat of the traditional automobile. The vibration-damping seat comprises a lower supporting seat, an upper supporting seat and a backrest which is connected with the upper supporting seat, wherein an intersection component is arranged between both sides of the upper supporting seat and the lower supporting seat, a spring is arranged between the upper supporting seat and the lower supporting seat, and a plurality of dampers are symmetrically distributed between the upper supporting seat and the lower supporting seat. The vibration-damping seat can effectively damp the impact of the front direction and the back direction of the seat and has good applicability; buffering can be realized prior to vibration damping, and the vibration-damping effect is good; and the elevation of the backrest is adjustable, and the comfort of the seat is enhanced.

Description

technical field [0001] The invention belongs to the technical field of machinery, and relates to a shock-absorbing seat, in particular to an automobile shock-absorbing seat. Background technique [0002] With the rapid development of the automobile industry, users have higher and higher requirements for the NVH performance of automobiles. The industry abbreviates noise, vibration and comfort as NVH (Noise, Vibration, Harshness), collectively referred to as the NVH problem of vehicles. Major automakers have invested a lot of money in researching and improving vehicle NVH performance to establish their brand image. At present, in order to improve the noise and vibration performance of automobiles in the domestic and foreign automobile industries, major companies have successively developed emerging NVH technology products such as semi-active suspensions, active suspensions, air springs, hydraulic mounts, and variable magnetic flow hydraulic mounts. It also introduces hydrauli...

Problems solved by technology

At present, in order to improve the noise and vibration performance of automobiles in the domestic and foreign automobile industries, major companies have successively developed emerging NVH technology products such as semi-active suspensions, active suspensions, air springs, hydraulic mounts, and variable magnetic flow hydraulic mounts. It also introduces hydraulic and electronic technology into the NVH field, overcoming the defect that traditional mechanisms cannot adapt to improve vehicle performance

As the final transmission object of the user, the seat has a good or bad vibration isolation performance, which directly affects the comfort of the occupants, thereby affecting the sales of automobiles.

[0003] Traditional seats generally use springs and (or) foamed plastics to dampen vibrations, and this damping material itself has some shortcomings: the foamed plastics block has po
